Pseudobombax ellipticum (White Flower)
A Mexican tree that often forms a globose caudex from the size of a cantaloupe to several feet across, when grown in restricted spaces such as rock crevices on cliff faces. This form of 'natural bonsai' is highly desired by plant collectors. The swollen trunk becomes marked with a tortoise-shell pattern in larger specimens, has green branches and large, deciduous, palmately-compound leaves, and shaving-bush like white flowers. Seedlings can be pruned to eventually form a substantial caudex, but if left untrimmed, it wants to become a full sized tree. Planted in the ground and not trimmed, it will do so!
